Tea/Z1 whom it mainconcern.-

- Be it known thatI, WILLIAM PITT CAN-Nine,

aeitizen of the United States, residing atliowell, in the county of Middlesex and Common-v wealth of- Massachusetts, have invented certain new andnseful tion, reference being had therein to the. accompanying drawings.

My invention consists in to act or discontinued, or whenever a lap forms itself which wilLnot become straightened out on its arrival at the sliver-guide.

I The inventionresides, more particularly, in

certain features ofznovelconstru ction and combination, all as hereinafter isexplained fully with reference to the iaccompanying drawings, andas afterward is more particularlypointed out and distinctly defined in the 'claimsat the close ofthis specification.

Fig. 15, Sheet '2, is a view "of the parts and construction which are shown in Fig. 11, looking atthem from the right-hand side in the latter figure, with a small part of At 1, Fig. 1, is apart of the fixed framework of a machineforpreparing slivers, At 2 is a cross-rail attached, to such framework.

- At 1.2 is a rotatingjroll, which is te'rm ednsually the electric roll, and at 13 is oneof the p'resser-rolls which rest on 12. A series 15,Sheet2.- l

At 11, Fig. 1*, is showna sliver.

occasioned by the separationof the 1'011'13 from the roll 12 by the material passing be tween them, so. that no metallieeontact occurs. comes discontinued, the 101113 is permitted to touch-the roll 12, whereupon the circuit is the shipping mechanism is brought into action to stop the machine. in part the electrical connections extending to the rolls 12 and13 arethroughthe metallic portions of the machine, proper care being taken to insulate those parts which pertain to one branch of the circuit froni those pertaining to the other branch thereof. Thefirst portion of my invention has refer ence to the manner of supporting the presser rolls in position, and describe the same. g

' At 3, Figs. 1,. 5, and G, 'is a stand which .thereto by bolts 4:, one of which is shown in Fig. 1, the said bolts passing through holes 301 301 in lugs 30 30, Fig. 5, which areforined on the opposite ends of the stand 3, and also through similar holes in rail H A nut 5 and the casing of the'electro nagnet'broken away.

said electric roll of presser-rolls is shown in Fig.

Aseustomar the rolls 12 and l3'are in elec-. trical communication, respectively, with op posite terminals from a source'of electrical" energy. "Normally a break in the circuit is \Vhen, however, the said material be I now will proceed to applied to the cross-rail 2 and is secured MASSACHUSETTS,"ASSIGNOR To; THE

enguide "or rail is Fig.'1at,Sheet 2, is a view simi to Fig 1, showing a modificompleted, the'eleetromagnet is energizedand loo faces forcontact with the surface 306 on the vremoval of 761, Fig.

the sliver-guide 7 is embraced in the electric circuit on the same side of the break therein as the electric roll 12. The sliver-guide 7 is formed or furnished with a wing or extension 71, (see liigs. 1, 2, and 3,) which extends beneath the electric roll 1; and into closeproximity thereto. Should a roll-up or lap of one or more slivers occur on the said electric roll 12, the accumulation of material will bear against the said wing or extension 71 and will operate to turn the sliver-guide 7 upon its pivots, thereby eifecting contact at the other side of the break in the elcctric'circuit, Preferably I cause the contact to be made with one of the rolls 13. To this end one extremity of a rod or pin 10 is fitted into a socket in the sliver-guide and secured therein by a clamping-screw 11, (see Figs. 1, 2, and 4,) its free end projecting into proximity to the desired one of said rolls 1.3.

At 77 is a stop-finger, which is shown separately in Fig. 13, Sheet 1. It is applied to the sliver-guide 7 and is arranged to coact with a stop 78, constituted by the head of a screw, so as thereby to determine the normal position of the sliver-guide 7, these devices serving to hold wing 71 just out of contact with the electric roll 12 in order to avoid the wear which would result from'contact of the said wing with the moving surface of the said roll.

washer 6, Fig. 1, are applied to the threaded nd of each of the bolt-s4. Sheets of insuating material 230 230, Fig. 1, are placed on' he opposide sides of rail 2, between the said tides and the proximate surfaces of the lugs 30,-'and of theheads of the bolts 4, to insulate the said bolts .4 and stand from rail 31', Fig. 1, is one of a series of standards which are secured to the stand 3, there being such a standard provided in connection with each presser-roll. Each presserroll rests upon the electric roll 12 and lies in the space or angle between the latter roll and the corresponding standard 31, the said standard having lateral wings 311 311, 0, 10, and 11, against which the surface of the presserroll bears and by which the axis of the presser-roll is held parallel with that of roll 1-2. The saidwings contact with the said surface at opposite sides of the circumferential groove 131', which is formed in roll. 13, the said groove being occupied by a projection 312 on the standard, which projection holds the Presser-roll from longitudinal displacement. The standards 31 are widened at their lower ends by forming them with wings 313 313, Figs. 9 and 10, which give extended surstand 3 to which they are applied, thereby securinggreater stiffness and'steadiness, each, standard being secured to the stand by a bolt or screw 32, the threaded endof which enters a threaded hole 314- in the standard. The boltsor screws 32 pass through open-ended verticalslots- 305 in the 'stand- 3, (see Fig. 5,) thus providing for theready application and the standards, and also for the vertical adjustment thereof to bringtheir upper ends into contact with the surfaces of the presser-rolls 13 at the desired height.

The second portion of my invention has reference to effecting a stoppage ofthe machine when a roll'up or lap occurs on the electric roll 12, and also when a knot or entanglement in one of the slivers presents itself, and I will now proceed to describe the same. 2

At 7, Figs. 1, 2, and 3,,Sheet his a sliver guide or rail. 'It is formed with openings 8 therethrough, for the passage of the slivers and is mounted pivotally upon the stand 76, which latter is secured to the rail 2 by a bolt 763, (see Fig. 12, Sheet 1,) the said bolt having applied to thethreaded end thereof the nut 76; and washer 765. The said sliverguideis pivoted upon pins 72, Fig. 1, which pass into holes 721 in the sliver-guide, and also pass through holes 567, which are made through the upwardly extending lugs 761 12, on the stand 76. To permit the sliver-guide to be adjusted endwise to the extent which may be required in order to locate the sliver-passages in proper position relatively to the presser-rolls 13, the stand 76 is formed with a longitudinal slot at 762 for the reception of the bolt 763, which secures it to rail 2. Through its supporting devices at the right of the pivots 72 in Fig. 1, so that the body of the sliver-guide and pin or rod 10 carried thereby naturally gravitate away from the rolls 12 and 13 until arrested by the stop devices 77 and 7 8. y The openings 8 through the sliver-guide are large enough to permit fre'e passage' of slivers in their normal condition, but should knots or entan glements occur in the slivers and not straighten out on or before arriving at the sliver-guide such knots or entanglements. will bedetained by the sliver-guide and the continued strain on the slivers will operate to cause the sliver,- guide to swing forwardly on its pivots until the adjacent presser-roll 13, whereupon the machine will be arrested. I

The electrical devices whichcoact with the foregoing to effect the'stopping of the machine are or may be of any suitable and approved character and construction. I will now proceed to describe those which I have shown in the accompanying drawings.

One wire 42 leads from'the electromagnet 19 to a binder-screw 28, the stem of which passes through the shell of frame or case 18, it being insulated therefrom by the washers 41-and 29 of insulating material, said stem entering a metal block 281 having a binder-screw 282, which secures 7 one end of a wire 15, the latter having its opposite end applied to a hole 302 in stand 30,

where it is secured by screw 304, fitted" to a threaded hole 303 in the said stand. A second wire43 extends from the electromagnet to a contact-plate 44, said contact-plate being separated from the exterior of the case or frame'18 by insulating material 53. A sec- 0nd contact-plate 49 is secured to frame 1, it being separated therefrom by. insulating ma-- springs are moved, thereby breaking the circuit between the contact plates 44 and 49.

g At 52, Fig. 1, is indicated, conventionally,-

a battery, and 51 16 are wires leading therefrom to the contact-plate 49 and one of the covers 17, respectively.

The modification which is represented in Figs. 14 and differs from what has been-described chiefly in that the rod or pin 10 on the sliverguide is replaced by a lug or pin 109, which is integral with the said and also in having'a different.means of supporting the preSser-rolls 13 in position. In these figures each of the presser-rolls has journals 133 at itsopposite ends, which are received in notches 132, provided in the arms erally under the of stands 319. The said stands have arms which project into the spaces between the ad- ;jacent ends of the said presser-rolls.

, I deem the construction which is shown on Sheet 1 better than that shown in Figs. 14 and 15, inasmuch-as in the former the rolls have no journals and there are no arms projecting into the spaces between the adjacent ends of the presser-rolls. Thus the said construction has nothing to catch and retain fibers at the ends of the rolls, and in placing a sliver under one of the presser-rolls it may be passed down at the end of such rolland carried latsame without it being neces f sary to remove such presser-roll from the ma;

chine. This feature of the invention is especially advantageous in cases where there are unanylarge cans at the back of the machine.

Former constructions of electric stop-motions sliver-guide,

render it needful for the operative to displace such cans in order to reach the Presser-roll and to'remove it in 'piecin g up.

'The stand 319, (shown in Fig.14,) has a foot or base which rests upon a rail 308, car- .ried by astand 309, which latter is insulated from 'rail 2 andbolted to the'same. Lugs 316 31 8 extend down fromsaid foot or base on opposite sides of rail 308, and a'clampingescrew 317 passes upwardly in an inclined direction through lug 318, it taking'bearing by its end against the under side of rail 308 and serving to secure the stand 319to the said rail.
